CHAPTER 4
MAINTAINING THE INTERACTIVE WHITEBOARD SYSTEM
Do not spray cleaners, solvents or compressed air directly on the projector. Do not use
l
spray cleaners or solvents near any part of the projector because they can damage or stain
the unit. Spraying the system could spread a chemical mist on some of the projector's
components and lamp, resulting in damage and poor image quality.
Do not allow liquids or commercial solvents of any kind to flow into the projector base or
l
head.
If wiping the mirror cover is unavoidable, wear protective gloves and gather the cleaning
l
cloth into a ball. Gently run the cleaning cloth across the lens mirror from the center to the
edge, using the cleaning cloth as you would a feather duster. Don't apply pressure to the
mirror cover.
IMPORTANT
When cleaning the interactive whiteboard system:
l
Wipe the exterior of the projector with a lint-free cloth.
o
If necessary, use a soft cloth moistened with a mild detergent to clean the projector
o
housing.
Do not use abrasive cleaners, waxes or solvents.
